摘　　要：针对污染场地背景下岩土工程地质勘察中水文地质勘察评估存在的问题,文章研究一种新的污染场地环境岩土工程地质勘察中水文地质条件评估方法。采用三维稳定流数学模型构建污染场地地下水污染物溶质运移模型,掌握污染物迁移的时间、范围和发展趋势;依据“源-径-汇”模式建立影响评估指标体系,使用熵权法计算各指标权重,通过多层次水位地质条件评估模式进行评分。实验表明:该方法可准确获取污染场地污染源的种类、范围和分布情况等,能够动态评估污染场地环境下水文地质条件,增加评估结果的科学性与准确性。This paper studies a new method for evaluating hydrogeological conditions in geotechnical engineering geological surveys of polluted sites,in response to the existing problems in hydrogeological survey and evaluation under the background of polluted sites.It uses a three-dimensional stable flow mathematical model to construct a solute transport model for groundwater pollutants in polluted sites to calculate the time,range,and development trend of pollutant transport.An impact assessment index system is established based on the“source path sink”model to calculate the weights of each index using the entropy weight method,and score through a multi-level water level geological condition evaluation model.The experiment shows that this method can accurately obtain the types,ranges,and distribution of pollution sources in polluted sites.The hydrogeological conditions in the polluted site environment are calculated dynamically,increasing the scientific and accurate evaluation results.
